When I went there in June last year there were several non-UK people on the course, including a French guy and a Swedish guy. Both are now flying in their own country, so I am sure it wouldn't be a problem.
I had a great time there and completed my PPL in 17 days. I spent as much as I was quoted - I found no hidden costs - everything was quoted upfront.
You will only get out what you put in. I did all my written exams at home, so was able to concentrate on the flying while there, but that was just me. Most did the exams there.
Hope it helps.
